Observation on the Efficacy of Skin Closure by Skin Staplers in Extended L-Shaped Incisions for Calcaneal Fractures

Objective This study aims to evaluate the effectiveness of skin staplers for wound closure following extended L-shaped incisions in the treatment of calcaneal fractures. Methods A retrospective analysis was performed on 82 calcaneal fracture cases (Sanders types III-IV) that underwent extended L-shaped incisions at the Second Hospital of Shanxi Medical University from June 2022 to March 2025. Out of these, 60 cases met the inclusion and exclusion criteria. A non-blinded, open, randomized controlled trial was conducted, assigning patients to either the stapler group (n = 28) or the Allgower-Donati group(n = 32). Key parameters assessed included wound closure time, postoperative inflammatory reaction area, skin temperature changes at the incision corners, and wound healing grades, which were then compared between the two groups. Results At the two-week postoperative follow-up, when sutures were removed, no significant differences were found in terms of inflammatory reaction area, skin temperature changes, or wound healing grades between the two groups. However, the stapler group demonstrated a notably shorter wound closure time (10.89 ± 2.87 minutes) compared to the Allgower-Donati group (20.44 ± 2.01 minutes). Conclusion The use of skin staplers for wound closure provides healing outcomes that are comparable to those achieved with the Allgower-Donati suturing technique in extended L-shaped incisions for calcaneal fractures. Importantly, the skin stapler method significantly reduces wound closure time (P < 0.05), which can lead to shorter overall surgical durations and a decreased risk of wound infections.
